The Other One - Episode Guide

Comedy about a girl called Catherine Walcott. And another girl called Catherine Walcott. Sisters who had no idea the other existed until their father dropped dead. Cathy has a fiance, a Duke of Edinburgh Award and a pension. Cat has a pay-as-you-go phone. The only things they have in common are their names (a smart move if you have got a secret daughter). Both of them have always wanted a sister - just maybe not each other.

Cathy and Cat cannot find their dad's will and, at their joint birthday party, their mums war over which family their dead dad loved most.

Cathy is forced to take compassionate leave from work but can't bear to tell Tess, so Cat let's Cathy hide at her house and throws her a party to cheer her up.

Cathy proposes they get Colin a memorial bench but, as Cat doesn't have the money, she has to improvise. Cathy also agrees to teach Cat how to ride a bike, with disastrous results.

With her mum refusing to go, Cathy's hen do invitees are Auntie Dawn, Marilyn, Cat and an old school friend. It doesn't turn out to be the classy, edifying affair Cathy wanted.

It's the night before the wedding but Cathy can't enjoy her drink-up as she's obsessed by a scuff on the wall Marcus made, and the sisters run in to Cat's old school bully.

Cat decides to take Cathy on their own sister honeymoon to cheer her up. Marilyn finds Colin's missing will and, together with Tess, they need to tell the girls the shocking news.

Catherine 'Cathy' Walcott and Catherine 'Cat' Walcott only discovered one another existed after their dad dropped dead. Having finally come to terms with the fact they are sisters, they are now reeling from the news that they also have a brother, Callum - and that Cathy just snogged him. As Cathy struggles with the ethics of fancying a sibling, Cat is determined to welcome Callum to the family, while Callum isn't sure what family means any more.

Cat's mum, Marilyn, is furious to learn she wasn't Colin's only mistress and sets about tracking down his other secret lover, Angela, starting a chain of events that nobody expected. Meanwhile, Cathy's mum, Tess, decides to have some fun with her late husband's legacy and embarks on an ill-advised luxury spending spree.

Cat reignites a feud with rival delivery driver Patience, putting her job on the line.

Meanwhile Cathy's surprising marital status causes trouble at her workplace, and as she finds herself unfairly passed over for a promotion by boss Jennifer, her frustration ends in humiliation and a head injury.

Angela is fast turning into the houseguest from hell for Marilyn, as she boozes away the grief of being rejected by her husband and her son. Plus with no sign of Colin's elusive pension money, Tess is having very little fun on her singles holiday in Morocco.

Cat & Cathy go to an adult maths GCSE class where the sexy teacher causes ructions. Tess takes a job in the worst place possible, and Angela resorts to kidnap to win back Peter.

Cathy is excited to introduce her siblings to lambing season at Auntie Dawn's farm, but Tess brings along an unwelcome visitor and Cat brings an unwise gift.

In a bid to heal his rift with Angela, Callum is lured to an eventful Northern Soul Revival. Next day, their Dad Colin still has surprises for his family from beyond the grave.
